Hello everbody! Not sure if this is the correct place to create this topic, if it's not please let me know and I'll move it. I'm looking at building a storage server for my business and I am doing it together with another business in town (aka partner). The server is going to be located at my office but my partner's data is very sensitive. This is the reason he wants to have his own server instead of buying just storage space online. His demand to be able to share this server with me is this: He is the only one that can access his data. So even though the server is in my office there is no way for me to get access to his data. Obviously I have to have my data on the server as well and we already have a third person that is interested in having acess to the server if I can guarantee this. The amount of data that my partner and the third person have is not that much, I do have a lot of data however. I hope I have explained this good enough, if not just ask for details and I'll try to give them to you. Thanks in advance!
